IIRC from reading about it, you just tick a checkbox next to all of the friends you'd like to bang; if one of them is using the app and ticks your as well then you're both sent a message. Presumably then a really awkward conversation occurs.

Also I don't think the kind of people who use an app like this are going to be aware of the fact that banging friends leads to less friends and weirder connections.
